Dear Keith,

On behalf of Calumet GP, LLC I am pleased to extend to you this offer to join us as EVP, Chief Financial Officer (CFO) and Principal Accounting Officer. You will be located at our Indianapolis, Indiana location and will report to me. Your start date will be Monday, October 28, 2019.

Your starting annual salary will be $425,000. You will be eligible to participate in the Calumet Annual Bonus Plan with a bonus target of 150% of your annual base salary based on company financial metrics and your own individual contributions. If minimum financial metrics and minimum individual contributions are met, it would pay at 50% of your base salary and at its maximum it would pay at 200% of your base annual salary. If actual performance falls between the various levels (between minimum and target for instance), the annual bonus award will be prorated, up to the maximum potential award. Should the Company not meet its minimum financial target, no awards will be issued regardless of individual contributions. Your participation in the Plan will commence on January 1, 2019 at the start of our fiscal year and be prorated accordingly if you start work after that date. Any award earned under this Program will be paid 50% in cash and 50% in fully vested phantom units which you must hold for a minimum of 3 years.

For a sign-on bonus, Calumet will match any purchases of CLMT units that you make in the open market according to the following conditions. You agree to conduct your purchases in accordance with our insider trading policy. Our match will apply to your purchases from your start date through the first 12 calendar months, equivalent to $500,000 that we will match unit for unit in “company match phantom units.” Our match will be grossed up for taxes. Your right to receive these company match phantom units will not be subject to any other performance standard. At the end of months 3, 9 and 12 of your employment, we will deliver you the number of fully vested phantom units equal to the number CLMT units you purchased during the preceding three or six month period, as applicable. If you are terminated without cause, the company match phantom units earned but not yet delivered will be delivered immediately following termination. Within two years from your start date and for the duration of your employment with Calumet, you agree to maintain the equivalent of twice your annual salary in aggregated value of CLMT units and/or company match phantom units.

You will also be eligible to participate in the Calumet GP, LLC Amended and Restated Long-Term Incentive Plan. Your annual LTIP target will be 60% of your annual base salary and these units have a 3-year cliff vest requirement. Any award under the Plan will take into consideration your individual contribution as well as the achievement of Company financial targets. Should the Company not meet its minimum financial target, no awards will be issued under the Plan.

As a salaried, exempt full-time employee you will be eligible for all benefits currently available to full-time employees of Calumet, including the Group Health Care plan, Life and AD&D Insurance, Long-Term Disability income Insurance, Retirement Savings Plan, which has a current Company match of 100% on the first 4% employee contribution and then 50% on the next 2% employee contribution. You

will also be eligible for the Calumet Deferred Compensation Plan with its generous match. For every $1 you contribute from your tax deferred bonus, the Company contributes a match of 33%. Relocation benefits will be agreed by both parties to optimize tax liabilities and will cover moving your household goods, travel arrangements for your family and new home purchase assistance. One month of temporary living expenses are included in your relocation benefits (including temporary housing), and an additional 5 months of temporary housing benefits will also be included.
